@MOd0 you can pass title_bar_color to View.present().

title_bar_color to View.present().

Tkanks for tell that, I became capable of change default bar_color.
i pleased.

but, how can i change "title_bar_color" when running program like when change "background_color" ,(for example label,button,,,).

for example i want change "title_bar_color" like that

1. red (when start progrum)

↓

2. blue ( when "button1 = sender.superview['button1']" pushed)

↓↑

3. green ( when "button2 = sender.superview['button2']" pushed)

This works decently.

import time, ui

class Interface():

	@ui.in_background
	def Switch(sender):
		if Interface.bgcolour == 'red':
			Interface.bgcolour = 'blue'
			Interface.btn.title = 'Red!'
		else:
			Interface.bgcolour = 'red'
			Interface.btn.title = 'Blue!'
		Interface.v.close()
		time.sleep(1)
		Interface.v.background_color = Interface.bgcolour
		Interface.v.present('sheet', title_bar_color = Interface.bgcolour)

	btn = ui.Button()
	btn.title = 'Blue!'
	btn.x = 0
	btn.y = 0
	btn.width = 300
	btn.height = 300
	btn.action = Switch

	bgcolour = 'red'
	v = ui.View(background_color = bgcolour)
	v.add_subview(btn)
	v.width = 300
	v.height = 300
	
x = Interface()
x.v.present('sheet', title_bar_color = 'red')

You need to resort to objective c to do this....

@lachlantula
Thanks for tell me that add subview with changing bar_color.
I learned python grammar which i didn't know until now.

@JonB
